Slate Tiles

Slate is sedimentary rock made of many layers of clay and volcanic ash. Slate tiles are made from thinly cleaved layers of the sedimentary rock. The low water absorption rate of slate makes it a durable and long lasting roofing material. It is not uncommon for a slate roof to last 100 years depending on the thickness of the slate.

Slate tiles come in a variety of shapes and patterns and range in thickness from 3/8 inch to 3/4 inch. Slate quarried in Vermont exhibits chemicals and mineral profiles that produce a variety of rare colours: grey, grey black, red, purple and green.

Because there is no roofing material that is heavier than slate tiles, special consideration is required to ensure your building can support the weight.

Slate tiles can be installed using hooks to hold the tile in place or the slate tile can be fastened to the decking with copper or stainless steel nails. Some argue that hooks are better than nails because with hooks no fastener penetrates the tile. However, the hooks are visible and may detract from the roofs finished look.

Slate roofs are costly. It takes a long time to install a slate roof properly and the materials are expensive. It is important that you choose a roofing company with the right experience and skill set.
